the rod 20 so that the relative position of the quadrants of the platele; may he determined by the operator in the vehicle without leaving thecar and raising the coveringhood over the engine. The extended portionof the rod 20 insidelthe dashboard is slightly enlarged to provide a cup24, having a knul-led cap 25, closing the same, so that a suitablepriming fluid may be injected there` in and pass down through the rod20, the flexible shaft 21, and into the boss 19 disposed on the top ofthe quadrant plate. A suitable hollow stem 26 extends .down -from the.open portion of the boss 19 through the plate and disk and into thechamber of the shell l0.` A coiled expansion spring 27, surrounding thishollow stem, is held in position by suitable Washers and a pin 28 tappedtransversely through said stem. As will be` understood'7 the primingfluid after reachingP the boss 19, will pass through the top of thevalve, through the hollow stem 26 and drip the manifold into the lowerportion of the shell l0, 'where it will be discharged through the pipeil into dof thc motor. ln order to prevent dust, sand and smallparticles of foreign matter passing through the openings in the disk 11and reaching the carburetor of the engine, thereby causing inconvenience-and necessitating adjustment, l 'prefer to place a quantity of steel orglass wool 29, or other suitable material, in the bottom of the shell l0in order to not only strain the priming fluid that may be injected intothe device, but also to iilfer the air passing I through the controlvalve into the manifold,

'While I have herein described and illustratedl certaininstrumentalities for carrying out my idea, it, of course, will beobvious to others skilled in the art, that modiications thereof may bemade without materially departing from the spirit of my invention, as,for example, the valve shell may be made o conical shape or shape likethe ordinary pet-cock, or in lieu of the steel wool, a stramer gauze maybe placed in a convenient position inside oi" the shell l0, and diversmeans may be employed to rotate the quadrant plate or the dish ll may berotated and the quadrant plate retained in stationary position. ltherefore desire it understood that all such moditications or changesare contemplated as included within the scope of my invention as setforth in the appended claims.,

What l claim isz-- l. ln combination with an internal coinvbustionengine .tor motor vehicles, an auxperforations, and a movable quadrantplate coacting with the first-mentioned plate and operable from thedash-board yof the vehicle whereby the adjustment oit said movable plateis adapted to uncover perforations in said closure plate.,

3. A combined air control valve and` primer for gasengines Lt'ormo'torvehicles comprising a shell open at one end and provided with adischarge orifice, means supplying priming fluid to said shell from thevehicle dash-board, a perforated plate adjacent the open end of saidshell, and e. rotatable plate coaching with said perforated. plateAwhereby the quantity of air entering said shellv therethrough isincreased or diminished. i

tl combined air control valve and primer for gas engines for motor'vehicles comprising a shell open at one end and provided with adischargerit-cda duct leading from the dash-board ot the vehicle to saidshell whereby priming fluid is adapted to be discharged into said stell,a plate dis posed in the open end of said shell and provided with aplurality et radiating series oi? perforations upon oppositey sides otthe axis of said plate, and a rotatable quadrant plate coactine' with.said perforated plate whereby the adjustment of said rotatable plate isadapted to uncover predetermined seriesot perforations in said closureplate.,
